Coastal living boosts physical activity, study shows

Coastal living boosts physical activity, study shows

People who live close to the coast are more likely to meet physical activity guidelines than inland dwellers, finds a new study released today. The research involved participants from across England and describes a particularly noticeable effect on western — but unexpectedly not eastern — coasts of the nation. Continue reading

Drug-infused nanoparticle is right for sore eyes

Drug-infused nanoparticle is right for sore eyes

For the millions of sufferers of dry eye syndrome, their only recourse to easing the painful condition is to use drug-laced eye drops three times a day. Now, researchers from the University of Waterloo have developed a topical solution containing nanoparticles that will combat dry eye syndrome with only one application a week. The eye drops progressively deliver the right amount of drug-infused nanoparticles to the surface of the eyeball over a period of five days before the body absorbs them. Continue reading

What’s your status? Health risks of low social status

What’s your status? Health risks of low social status

In western society, where keeping up with the Joneses — or, better yet, surpassing them — is expected and even encouraged, status matters. So important is it that for many people, physical and emotional wellbeing are directly connected to their place in the social hierarchy Continue reading

What’s your status? Health risks of low social status

In western society, where keeping up with the Joneses — or, better yet, surpassing them — is expected and even encouraged, status matters. So important is it that for many people, physical and emotional wellbeing are directly connected to their place in the social hierarchy. That’s hardly news to anthropologists at UC Santa Barbara, but they were taken by surprise when research findings indicated that the same relationship exists among the Tsimane, an egalitarian society of forager-farmers in the Bolivian Amazon Continue reading

Reproducibility score for SNPs associated with human disease in GWAS

Reproducibility score for SNPs associated with human disease in GWAS

To reduce false positives when identifying genetic variations associated with human disease through genome-wide association studies (GWAS), Dartmouth researchers have identified nine traits that are not dependent on P values to predict single nucleotide polymorphisms (SNP) reproducibility as reported in Human Genetics on October 2, 2014.

Amputees discern familiar sensations across prosthetic hand

Amputees discern familiar sensations across prosthetic hand

Even before he lost his right hand to an industrial accident 4 years ago, Igor Spetic had family open his medicine bottles. Cotton balls give him goose bumps Continue reading

Mind-controlled prosthetic arms that work in daily life are now a reality

Mind-controlled prosthetic arms that work in daily life are now a reality

For the first time, robotic prostheses controlled via implanted neuromuscular interfaces have become a clinical reality. A novel osseointegrated (bone-anchored) implant system gives patients new opportunities in their daily life and professional activities. In January 2013 a Swedish arm amputee was the first person in the world to receive a prosthesis with a direct connection to bone, nerves and muscles. Continue reading

Conspicuous tRNA lookalikes riddle the human genome

Conspicuous tRNA lookalikes riddle the human genome

Transfer RNAs (tRNAs) are ancient workhorse molecules and part of the cellular process that creates the proteins, critical building blocks of life that keep a cell running smoothly. A new discovery suggests that the number of human genomic loci that might be coding for tRNAs is nearly double what is currently known. Most of the newly identified loci resemble the sequences of mitochondrial tRNAs suggesting unexpected new links between the human nuclear and mitochondrial genomes, links that are not currently understood Continue reading
